Computer mouse suddenly card what's going on

1. Pull out the mouse and plug in, sometimes the USB power supply is insufficient, there will be this situation.

2. What is the system installed software in the background to occupy a higher CPU or IO, resulting in the machine is not responding, may also be machine poisoning. The way to respond is to run the program less or kill and uninstall the exception process!

3. Start up and run with a large memory footprint. can use the optimization master, cleaning assistants and so on system garbage clean-up, not by the commonly used software to uninstall and so on. Computer Trojans and viruses can also react this way.

4. For a new mouse to try whether it will be so, and then look at the control Panel has a mouse option, the speed to be transferred to the middle of the good!

1 Mobile Not flexible

Mobility is not flexible refers to the mouse when moving, the corresponding pointer on the screen does not follow the move. Under normal circumstances for a large mobile mouse, the cursor can move normally, but a small range of mobile mouse, the cursor can not move. Large mobile mouse work normally, and small move when the work is not normal, indicating the normal mouse installation, circuit work is normal, the reason is the rubber ball can not effectively drive the grating disk rotation. This is rubber ball, left and right axis, front and rear axle and support wheel is too dirty, causing the rotation is not flexible caused. This is the most likely failure of the mouse. The handling of the fault, as long as the removal of dirt can be. The specific treatment is to flip the mouse, according to the direction of the arrow counterclockwise rotation of the active floor, remove the active bottom plate and rubber ball, and then the roller and support wheel, rubber ball on the dirt clean, reload can return to normal. Optical mouse because there is no rotating rubber ball, there is no rotation of the roller, so there is no flexibility due to the rotation of the mouse movement is not flexible phenomenon. However, when the light tube or photosensitive tube accumulated dust too much, also may cause the mouse movement is not flexible.

2 fails in one Direction the mouse moves in one direction only, and the other direction does not work, indicating that there is no rotation in one direction, or that a corresponding set of LEDs and photosensitive transistors has at least one damage. For mechanical mouse treatment, first rotate the active floor, remove the active bottom plate and rubber ball, and then use the hand to rotate the roller directly, if there is a roller can not rotate, or rotation is more difficult, indicating that the failure is due to the roller has not been caused by the rolling of the ball. The rollers may not rotate because they are stuck in the dirt, clean the dirt to remove the fault, if the two rollers are flexible and rotate with the hand, the cursor can still only move in the left or right direction, the fault is the corresponding light-emitting diode or photosensitive tube damage. Unscrew the fixed screw of the mouse, open the outer cover, check the resistance between the two poles of the photosensitive tube on line, if the resistance varies with the light intensity of the photosensitive tube, the photosensitive tube is good, the damage is the light-emitting diode. Otherwise the photosensitive tube is damaged, replace the damaged parts, the fault can be ruled out.
